- To all whom it may concern:

Be it knownthat I, GUSTAVUS A. BAUER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Dust-Collectors, of which the following is a specification.

My invention relates to dust collectors and may be best illustrated in connection with the device for collecting the dust derived from the operation of a pneumatic sweeping ap aratus.

ne form of my invention is illustrated in the accompanying drawings, wherein- Figure 1 is a longitudinal section; through the collector, Fig. 2, a cross section on the line 2-2 of Fig. 1; Fig. 3, a. front elevation. Like parts are indicated by the same letter in all the figures.

A. is a base or bed on which rests the cylindrical case B closed at one endby the fixed end C and at the other by the removable end D. This removable end D is hinged to the wall of the case by means of the hinge D Centrally mounted uponit by means of the bolt D is the disk 1) provided with a handle D and four radially extended eccentrically pivoted rods D D The outer end of each of these rods is ada ted to pass through aloop D secured to the end of the case. Thus this end cover of the case becomes a door adapted to be swung on the hinge and be locked in position when closed.

E is the supply pipe and F the discharge pipe whereby the current of air charged with dust is introduced into the collector and removed therefrom. The current of air is kept in circulation by means of the fan G diagrammatically shown in connection with the discharge pipe.

Within the case is a removable core consisting of the disks J, J each open near its up er side, as for. example, at the point J and a series of disk sections J J These several disks are held together by the longitudinal rods J J each disk bein held in position by the set nuts J 4 J At t 1e end of the rod are the intermediate short ipe sections-J J which surround-the rod and lie between the several disks. B this means the air introduced into the col ector is compelled to pass therethrough along the circuitous route indicated by the arrows. This passage takes place through and along the upper gather some of them a a te part of the case so that the lower part of the case, by means of the full sized disk, is divided into a series of settling chambers or compartmentswhere the air'is relatively free from motion. The heavier particles of dust fall into these chambers and are there collected. When the current has been running through the collector for a suflicient time to cause the deposit of a considerable amount of dust the flow of the current may be arrested, the door opened and the core removed. The front end of the core is provided with a handle K as indicated, for this purpose. The core, of course, operates to draw the collected dust out of the case where it may fall into any convenient receptacle.

I do not wish, of course, to be limited to the particular form, sha e and proportion of the Various elements orming my invention but I shall point out in my claims the large disk at the top could be arranged as deslred.

I claim:

1. A dust collector comprising a case having an inlet at one end and an outlet at the other, and a series of transverse diaphragms within forming relatively still settling chambers at the bot-tom, and a circuitous air passage at the top, said dia hra ms secured toto scrape the ttom and removable rom the case to scrape out the dirt.

2. A dust collector comprising a case having an inlet atone end and an outlet at the other, a series of transverse diaphragms Within forming relatively still settling chambers at the bottom and a circuitous air passage at the top, the alternate diaphragms extending to the 'bottom of the case and perforated near their tops, said diaphragms '-III together some of them adapted to scrape the bottom and removable from the case to scrape out the dirt.

4-. A dust collector comprising a case havin an inlet at one end and an outlet at the ot er, and a series of transverse diaphragms Within forming relatively still settling cham-.

bers at the bottom and a circuitous air passage at the to, alternate diaphragms extending to the hottoin but perforated at the top, and the other diaphragins importer-ate at the top hut not extending to the bottom said diaphra s secured together some 0 them adapte to scrape the nottom and removable from the case to scrape out the dirt.

5.. A dust collector comprising a case havin nn'inlet at one end and an outlet at the ot er, and a series of transverse diaphragms within forming relatively still settling chamhere at the bottom and a circuitous air passage at the top, alternate diaphragms of practically the same size as the cross section of the case, dperforated near the top and the remaining laphra s approm'mately half the cross section 0 the'case and filling the upper portion thereof, said diaphragms secured together some of them adapted to scrape the bottom and removable from the case to scrape out the dirt.

6. A dust collector comprising a case havin an inlet at one end and an outlet at the ot er, a series of transverse diaphragms within forming relatively still settling chamhers at the bottom and a circuitous air assage at the top said dia hra s secure toether some oi them a a to to scrape the ottom and removable rom the case, to scrape out the dirt and a door at one end of the case. 1

7. A dust collector comprising a case havan inlet at one end and an outlet at the ot er, a series of transverse diaphragms within forming relatively still settling chambers at the bottom and a circuitous air passage at the top, the alternate diaphragms extendin to the bottom of the case and perforate near their tops, said diaphragms secured together some of them adapted to scrape the bottom and removable from the case to scrape out the dirt, and a door at one end of the case.

8. A dust collector comprising a case having an inlet at one end and an outlet at the other, a series of transverse diaphragms Within forming relatively still settling chambers at the bottom and a circuitous air passage at the top, alternate diaphragms imperiiorate at the top but with lower edges above the bottom, said diaphragms secured toether some of them ado ted to scrape the ottom and removable rrom the case to scrape out the dirt, and a door at one end of the case.

9. A dust collector comprising a case having an inlet at one end and an outlet at the other, a series of transverse diaphragms within forming relatively still settling chambers at the bottom and a circuitous air pas sage at the to alternate diaphra s extending to the Bottom but perforate at the top, and the other diaphragms imperforate at the top but not extending to the bottom, said diaphra s secured to ther some of themada tef t o scrape the ottom and removable rom the case to scrape out the dirt, and a door at one end of the case.

10. A dust collector comprising a case havin an inlet at one end and an outlet at the other, a series of transverse diaphragms within forming relatively still settling chambers at the bottom and a circuitous air passage at the top, alternate diaphragms of practically the same size as the cross section of the case, erforated near the top and the remaining Liiaphra s approximately half the cross section 0 the case and filling the upper portion thereof, said diaphragms secured together some of them adapted to scrape the bottom and removable from the case to scrape out the dirt, and a door at one
